Important Compatibility Information:
This oil is intended only for pumps designed to receive periodic oil service. Many pressure washers use sealed axial-cam pumps that are lubricated at the factory and do not require pump-oil changes.
Before using this product, consult the pressure washer owner’s manual to confirm:
- The pump is serviceable
- SAE 30 pump oil is specified
- The required oil capacity
- The correct filling and draining procedures
- The recommended service interval
Do not use this product as pressure-washer engine oil unless the engine manufacturer separately specifies it. Do not overfill the pump, mix incompatible lubricants, or add oil to a factory-sealed pump.
